Cracked Bumper? Fix It the Smart Way.
A cracked fender is among the most frequent car body repairs completed by clever (Small) repair operatives. Frequently this kind of injury leads to scores, scuffs and scrapes which can be fixed easily and quickly by a mobile car body repair technician with lacquer, primer, paint and a few auto body filler. Occasionally however, a crack will appear and split the fender and this must be dealt with otherwise.
If a cracked bumper is not repaired or the repair is performed with regular filler, the bumper’s structural integrity is endangered. It is essential that the bumper fracture rejoined and is treated having a hard yet flexible resin. A special technique is used to execute this which should be carried out every time.
Generally the fracture will not appear severe, it often gets the appearance of a hairline crack and it is tempting to run a small filler as fixed, and treat that. The consequence of this is the next time the fender is put under any pressure whatsoever, the crack often widen and will reappear. The crack must be widened, efficiently worsening the damage so that there is enough of an opening for the resin. A hole is drilled at each end of the crack, half on and half off the very end. The crack forever ceases from running again. Next, a Alloy Wheel Repair Essex v-shaped groove must be made right down the crack’s centre, wide enough without going off the border of the crack, to make a hole.
A group of holes, one on each side of the crack every inch or so along the entire period of the crack have to be drilled. A strip of mesh is then placed on the inside of the fender all along the damage – this will hold the resin in place while it hardens and may be left there afterwards. A mix of hardener and resin, especially invented for bumper repairs such as this, is subsequently injected into each of the holes which were drilled. The purchase needed to prevent the resin going direct through is provided by the mesh backing. The goal here is to effectively “stitch” the repair together.
After applying the resin, a body filler spreader (or ideally specialist contouring film) is employed to smooth the repair on the top side of the fender to minimise the sanding which is demanded later. Care should be taken as the fender resin can melt if sanded vigorously. After the resin has fully hardened the bumper is structurally sound again and could be sanded, filled, primed, painted and lacquered as regular. Result – a perfect bumper repair
